Fix https://eclipse.dev/eclipse redirect to 404.html

[merks]

• It currently redirects to https://www.eclipse.org/errors/404.html but it would be better to redirect to portal, e.g.,
  https://projects.eclipse.org/projects/eclipse.platform
• More correct would be https://projects.eclipse.org/projects/eclipse but it's quite bogus in content.

FYI, I have tested this with my local host which serves the PHP like this if specified explicitly:

But if I enter this:

it redirects:

I expect the real server also given precedence to the index.html and will provide the redirection.

In any case, we really should take some type of action to fix this problem and this file shows how we can generally redirect any page (folder) to a different page.

This simple pattern allows one to express a redirection simply by placing this index.html in any folder.

Clearly we need to think about how to revamp the overall site(s), but we should minimally repair the project root folders if the project website is still being used to populate the contents of dev.eclipse.org...

@merks this is only a HTML redirect, it would be better to has a real transport level redirect as a HTTP 301 as otherwise e.g. google search results are likely not updated or even get a penalty.

Yes, I understand that this is not the best way and that some .htaccess thing is apparently better. But I'm not sure we're allow to do that ourselves in the website repository. In any case, this is simply an improvement over the abomination that has been in place for months now and seems to have no sign of ever being addressed by anyone.

Maybe we're allowed to author an .htaccess ourselves. We can ask about that on this issue:

For Tycho I asked the infra team and they set it up for the project.

For Tycho I asked the infra team and they set it up for the project.

I suspect that the fact that the content of this determines the contents of the website makes this a different beast:

https://github.com/eclipse-platform/www.eclipse.org-eclipse

But that's just a suspicion with no factual basis.

[akurtakov]

Is this one still needed or problem will be handled in another way?

[merks]

Apparently it could be handled in a different way by the foundation upon request, we could redirect like this, or we could create proper content at this page...

So it's up to you (or whoever else works to improve it). Anything is better than current state.
